M u -101mm concerns Be it'iknowmthhtfl'j Answer r Se man's,

a.v citizen? of tl'ie U-Ii' itd S tatesgresiding-at Illinois, have finvented new and useful Improvements in Dri-vi-ng Mechanism of which thefollowing Rdi 'Biidg' Randolph County;

isa'vfs eeitltiationf g r This invention relates te dsivingrmechmnisms,-and *l1asspe"ciat reference-- to dr'i ving. h mechanism?adap.ted= for the operation of domestic washing machines,althbughithvill atifonj; which" is strong. and durable? and whic'hgispractically noiseless in operation.

With the fo'regoingiiand other objects in view; my invention"may 'take:form 'in" dif ferenit embodiments; and? variations; only two'of'whic'h"Ihiirve, shbwwintliedrawings, in'whic t-r Fig... 1 iS -ELIL- elevationofu-Washing mm:- chine havingpne' forni of the invention in connectiontherewith.

Fig. 2 is a sectional view showing the gearing by which the washingmachine mechanism may be driven alternately in opposite directions.

Fig. 3 is a detailed view from the line 33 of F1 1, showing a form ofsupport which may e employed to support one of the shafts.

Fig. 4 is a view showing a diflerent arrangement of the shafting fordriving the washing machine mechanism alternately in oppositedirections.

Although I have shown only two variations or modifications of theinvention, it is obvious that the invention may take other forms and Ido not restrict my invention to the specific forms shown, or to anyspecific forms. My invention is as broad as the scope of the appendedclaims.

in the form of the invention shown in Fig. l, the shaft 1 of the washingmachine mechanism supports a wheel 2 having an opening I :it one side ofthe shaft l to perinit the gear by which the Wheel 2 is driven to movefrom on suit: to the other ()i said Wheel in order to drive szinl Wheelat ternately in opposite directions. The Wheel 2 is rovided with" anarcuate or circular} series of teeth 4 on its outer face and with asimilar series of teeth 5 on its inner face. If ileisired the'wheely2may be and as shown said whee is provided with a circumferem Mal-portionti'serving' as a track or support forthe entrained drivin'g device forthe purpose,' among; others; of preventing locking of the-"parts 'by'tooclose engagement.

As shown, there is a motor 7 arranged to drive a shttftS equipped with aworm or gear 9. The worm or gear 9 meshes with and drives a worm or gear10 which is attached'to a'shaft' 11 having a gear 12 thereon. The'gear12 meshes with and drives a gear lfl ivhich, in the'form shown, isloosely supported upon a shaft 14h The gear 13 may be-rlo'clred upon ashaft 14 a clutch member 15 movable on the shaft into and out ofengagement with the gear 13 by a lever 16. A universal joint 17 of knownor appropriate construction unites the shaft 14 with'a shaft 18 so thatthe shaft 18 is driven hy'the shaft 14. The shaft 18 issupported'inaiswinging support 19whic'h is 'capa-bleof sufiicientmovement to move the gear 20fon'said shaft 18 from one side to the-otherof the'whcel 2, as required to mesh the gear 20 alternately with theteeth 4 and 5. The car 20 moves from one side to the other of t e wheel2 through the open ing 3 so as to drive the wheel 2 alternately inopposite directions. As shown, the track 6 constitutes a support for thehub of the wheel 20, thus preventing locking engagement of the wheel 20with the teeth of the wheel 2.

Lateral movement of the pivoted support 19 is limited by stops 21 (Fig.3) which, as shown, may be adjustable so that the lateral movement ofsaid support may be accurately controlled. Springs 22 may be employed toimpart initial movement to the sup ort 19 when the opening 3 is oppositethe w ieel 20 and in position to. permit movement of the wheel 20 fromone side to the other of the wheel 2. Said springs 22 also serve tocushion and soften the force of the move ment of the support 19 so thatthe ijiperation of the marhine is reni'lcreil practicall noiseless.

in the IUUtllllClltlOIl or variation of the ill vention shown in Fig l,lhe shaft having the universal joint therein for driving the wheel isilriven from the gearing of the g) shaft 8. .is shown in Fig l a shaft23 by means of any or not, as desired. The gear or worm 24: is

in mesh with the gear or worm 9. shaft 26 is connected up with the shaft23 by a; universal jeinb 27. The equipment of the shaft 26 is the sameas the equipment of the shaft 18, there being a gear'28 on said shaft 26corresponding to the gear 20 on the shaft 18.v i

The-shaft 26 is supported for lateral movement by afsliding bearing 29nionnted in a gu'ide'30, lateral movement of said bearing being lini'ited by adjustable stopsv 31 similar to the stops 21. Springs 32 maybeemployed to soften and to silence the force of the m'venient aift e shaffii nd' p r initial mQ'veme-ncs thereto when it is] time for sai'd'shaft to move from one position to antithe f 1 Fi oin the foregoing itis a'p parentthat my invention serves all jof its intended objects ina'highly satisfactory manner As stated the iiivent ion may takediflerent forms. It is silentand durable in operation and may be usedadvantageously by unskilled persons.

[do not restrict myselfto unessentiallirnh tations, but what I claim anddesire to secure by Letters atent, i.s:

l. The combination with a gear to be ro- Lated alternately in oppositedirections, a rotary shaft, an additional shaft pivoted to said rotaryshaft and driven thereby, a gear in connection with said additionalshaft meshing with the first-named gear, a swing ing support for saidadditional shaft for swin ing said gear on said snail; too'pp'ositesides'of the first-named gear, springs for im- .rpartingeiinitiat'mnyelnent to said support when said support is to be moved, and stops 2.In gearing of the character described,
